Prestone DOT 3 Brake Fluid delivers enhanced performance vs. DOT standards, benefiting all vehicles calling for DOT 3. This synthetic fluid starts with a higher dry boiling point than the DOT minimum standard to protect against overheating, brake fade and performance decline due to water absorption.
Features:
50,000-mile extended life fluid, formulated to prevent corrosion of all metals within the braking system
High-performance formula for extreme braking, providing a higher margin of safety because of its high-temperature synthetic extended life formula
Prevents overheating, brake fading and exceeds DOT 3 standard requirements
Protects against performance decline due to water absorption. Prevents corrosion of all metals within the braking system

How do I know if my brake fluid needs to be changed?
Brake fluid absorbs moisture. Water in brake fluid can boil during repeated or extended braking, creating air bubbles which reduce braking effectiveness. Water also can corrode metal brake lines. Change your brake fluid when:
